Ultimately, you are responsible for getting copyright permissions and determining Fair Use. So, how do you figure out if your use is fair? You look at:
- how you're using the work;
- how much of the work you're using;
- what kind of work it is;
- and how your use will affect the market for that work.
These are called the "four factors" of fair use. See Columbia University's copyright website for more detailed information.
A fair use checklist is a tool you can use to help you decide if your use is fair.
A fair use checklist is a decision-making tool; in the end, you still have to make your own determination. What the checklist can do is let you know what kinds of things favor fair use and what kinds of things oppose it, giving you a framework for thinking about your use of a work. And, if you print it out and save it, it can provide documentation of your analysis (which can be helpful if anyone questions your decision).
